NBG2105 User’s Guide 13CHAPTER 1Introduction1.1 OverviewThis chapter introduces the main features and applications of the NBG2105.The NBG2105 extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE 802.11b/g/n compatible devices.A range of services such as a firewall and content filtering are also available for secure Internet computing. 1.2 ApplicationsYour can have the following networks using the NBG2105:•Wired. You can connect network devices via the Ethernet ports of the NBG2105 so that they can communicate with each other and access the Internet.•Wireless. Wireless clients can connect to the NBG2105 to access network resources. You can use WPS (WiFi Protected Setup) to create an instant network connection with another WPS-compatible device.•WAN. Connect to a broadband modem/router for Internet access.1.3 Ways to Manage the NBG2105Use any of the following methods to manage the NBG2105.• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your ZyXEL Device.• Web Configurator. This is recommended for everyday management of the NBG2105 using a (supported) web browser.1.4 Good Habits for Managing the NBG2105Do the following things regularly to make the NBG2105 more secure and to manage the NBG2105 more effectively.
Chapter 1 IntroductionNBG2105 User’s Guide14• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NBG2105 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG2105. You could simply restore your last configuration.1.5 Resetting the NBG2105If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET button on the underside of the NBG2105 to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the password and the IP address will be reset to the defaults shown on the cover of this user’s guide.1.5.1 How to Use the RESET Button1Make sure the power LED is on.2Press the RESET button for longer than five seconds (when the power LED begins to blink) and release it to set the NBG2105 back to its factory-default configurations.1.6 The WPS ButtonYour NBG2105 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the WiFi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.You can use the WPS button to activate WPS in order to quickly set up a wireless network with strong security.1Make sure the power LED is on (not blinking).2Press the WPS button for less than two seconds and release it. Press the WPS button on another WPS-enabled device within range of the NBG2105.
Chapter 1 IntroductionNBG2105 User’s Guide 15Note: You must activate WPS in the NBG2105 and in another wireless device within two minutes of each other. For more information on using WPS, see Section 8.2 on page 59.1.7 The Clone MAC ButtonYour NBG2105 can clone the MAC address of the computer connected to the NBG2105. It is recommended that you clone the MAC address prior to hooking up the WAN port or connecting to an AP or wireless router with Internet access.Note: MAC cloning is supported only when the NBG2105 is in Router mode.1.7.1 Cloning a computer's MAC address1Make sure the power LED is on (not blinking).2To copy and use the MAC address of a currently connected computer through a wired Ethernet or wireless LAN connection, press the Clone MAC button for two to five seconds and release it. 3The WPS/MAC Clone LED turns on when the clone was successful.4The NBG2105 restarts automatically ten seconds after you press the Clone MAC button.1.7.2 Restoring the default MAC address1Make sure the power LED is on (not blinking).2Press and hold the Clone MAC button for more than five seconds to reset the NBG2105 back to the factory default MAC address. The Clone MAC Address in the WAN screen shows 000000000000 to indicate the NBG2105 is using the factory default MAC address.3The NBG2105 restarts after you press the Clone MAC button.

Chapter 3 Operation ModesNBG2105 User’s Guide 293.6 WISP + UR ModeIn WISP (Wireless ISP) + UR (Universal Repeater) mode, your NBG2105 can act as a wireless client to wirelessly connect to the Internet or an existing network via an access point. In addition, it can provide Wi-Fi function to the clients on the LAN side. Use this mode if you want to wirelessly connect to the Internet or have an access point or wireless router in your network. In WISP + UR mode, the IP address of the device on the local network is 192.168.1.2.Note: Make sure your network and the remote network are NOT in the same subnet. If the access point or wireless router is using 192.168.1.x, the NBG2105 in WISP + UR mode needs to use something else, say 192.168.2.x.Note: When the NBG2105 is in WISP + UR mode, you still need to enter your ISP information in the WAN screen in order to access the Internet.In the example below, one NBG2105 is configured as WISP +UR mode (A) and another is used as an access point (B). The NBG2105 (A) wirelessly connects to the available access point (B), and can allow the clients (x and y) to access the network through it using a wireless connection. Figure 10 WISP + UR Mode Application3.6.1 Setting WISP + UR ModeSelect WISP + UR Mode if your NBG2105 needs a wireless client to connect to an existing access point, still have router functions, and also allow wireless clients to associate with the NBG2105.

Chapter 4 Router Setup WizardNBG2105 User’s Guide 35The following table describes the labels in this screen.4.3.3 WAN Access Type: PPPoE Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users.Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber's site.By implementing PPPoE directly on the NBG2105 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.Select PPPoE as the WAN Access Type to make the WAN port setup its IP configuration via PPPoE. Complete the fields described.

This example uses the NBG2105 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card).There are two WPS methods for creating a secure connection. This tutorial shows you how to do both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 8.2.1 on page 59.This is the easier method.•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NBG2105’s interface. See Section 8.2.2 on page 60. This is the more secure method, since one device can authenticate the other.8.2.1 Push Button Configuration (PBC)1Make sure that your NBG2105 is turned on and working as an AP or wireless router. Make sure that the device is placed within range of your notebook. 2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook.3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button)4Log into NBG2105’s Web Configurator and press the Start PBC button in the Wireless LAN > WPS screen.
Chapter 8 TutorialsNBG2105 User’s Guide60Note: Your NBG2105 has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other.Note: It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG2105 sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG2105 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG2105 and wireless client (the NWD210N in this example).Figure 38 Example WPS Process: PBC Method8.2.2 PIN ConfigurationWhen you use the PIN configuration method, you need to use both NBG2105’s configuration interface and the client’s utilities.1Launch your wireless client’s configuration utility.

NBG2105 User’s Guide 69CHAPTER 9LAN9.1 OverviewThis chapter describes how to configure LAN settings.A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses.Figure 40 LAN Example9.2 What You Can Do•Use the LAN Interface Setup screen to change the IP address for your NBG2105 (Section 9.4 on page 70).•Use the Active DHCP Client screen to see which DHCP clients have accepted their IP configuration from the NBG2105 (Section 9.4.1 on page 71).9.3 What You Need To KnowThe LAN parameters of the NBG2105 are preset in the factory with the following values:• IP address of 192.168.1.1 (Router mode) or 192.168.1.2 (non-router modes) with subnet mask of 255.255.255.0 (24 bits)• DHCP server enabled (Router mode or WISP+UR mode) with client IP addresses starting from 192.168.1.100 and ending with 192.168.1.200. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded Web Configurator help regarding what fields need to be configured.
Chapter 9 LANNBG2105 User’s Guide709.3.1 IP Pool SetupThe NBG2105 is pre-configured with a pool of IP addresses starting from 192.168.1.100 to 192.168.1.200. This configuration leaves 98 IP addresses (excluding the NBG2105 itself) under 192.168.1.99 for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have.9.3.2 LAN TCP/IP The NBG2105 has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.9.4 LAN Interface Setup ScreenUse this screen to change the IP address for your NBG2105 and configure the DHCP server.

NBG2105 User’s Guide 73CHAPTER 10WAN10.1 OverviewThis chapter discusses the NBG2105’s WAN screens. Use these screens to configure your NBG2105 for Internet access.A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.10.2 What You Can DoYou can configure your WAN interface to access your ISP in the following ways.•Static IP allows you to configure all NBG2105 WAN IP configuration settings manually (Section 10.4.1 on page 74).•DHCP Client allows the NBG2105 to get its IP configuration from a DHCP server (Section 10.4.2 on page 75).•PPPoE allows the NBG2105 to connect via the Point-to-Point Protocol over Ethernet (Section 10.4.3 on page 76).10.3 What You Need To KnowThe information in this section can help you configure the screens for your WAN connection.10.3.1 Configuring Your Internet ConnectionEncapsulation MethodEncapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet), they should also provide a username and password (and service name) for user authentication.
Chapter 10 WANNBG2105 User’s Guide74WAN IP AddressThe WAN IP address is an IP address for the NBG2105, which makes it accessible from an outside network. It is used by the NBG2105 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG2105 tries to access the Internet.If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method).DNS Server Address AssignmentUse Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG2105 can get the DNS server addresses in the following ways.1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.2If your ISP dynamically assigns the DNS server IP addresses (along with the NBG2105’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. WAN MAC AddressThe WAN port's MAC address can be configured by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Clear Mac Clone to select the factory assigned default MAC Address.Otherwise, press the Clone MAC address button on the side of the NBG2105 to clone the MAC address of the computer connected to the NBG2105. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.10.4 WAN Interface SetupClick Network > WAN to change how your NBG2105’s WAN interface accesses your ISP. The screen differs according to the WAN Access Type you choose.10.4.1 Static IPSelect Static IP from WAN Access Type to configure all NBG2105 WAN IP configuration settings manually.

PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius).One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.Table 34 Network > WAN: DHCP ClientLABEL DESCRIPTIONWAN Access Type Select DHCP Client to make the NBG2105 get its IP configuration from a DHCP server.MTU Size Enter the MTU (Maximum Transmission Unit) size for each packet.

Chapter 10 WANNBG2105 User’s Guide 77Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.By implementing PPPoE directly on the NBG2105 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.Select PPPoE from WAN Access Type to make the NBG2105 get its IP configuration via PPPoE.Figure 45 Network > WAN: PPPoE The following table describes the labels in this screen.Table 35 Network > WAN: PPPoELABEL DESCRIPTIONWAN Access Type Select PPPoE to make the NBG2105 get its IP configuration via PPPoE.User Name Enter the user name provided by your ISP.Password Enter the password provided by your ISP.MTU Size Enter the MTU (Maximum Transmission Unit) size for each packet.

NBG2105 User’s Guide 79CHAPTER 11Quality of Service (QoS)11.1 Overview Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-demand.Configure QoS on the NBG2105 to reserve bandwidth for certain traffic based on the IP address or MAC address. 11.2 QoS Setup ScreenClick Network > QoS to show the QoS Setup screen.Figure 46 Network > QoS

NBG2105 User’s Guide 83CHAPTER 13Wireless LAN13.1 OverviewThis chapter discusses how to configure the wireless network settings in your NBG2105. See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 48 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your NBG2105 is the AP.13.1.1 What You Can Do•Use the Basic screen to turn the wireless connection on or off and make other basic configuration changes (Section 13.2 on page 86).•Use the Advanced screen to configure wireless advanced features, such as the output power and set the RTS/CTS Threshold (Section 13.4 on page 88).•Use the Security screen to set up wireless security between the NBG2105 and the wireless clients (Section 13.5 on page 89).
Chapter 13 Wireless LANNBG2105 User’s Guide84•Use the Site Survey screen to scan for and connect to a wireless network automatically. (Section 13.6 on page 92)•Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 13.8 on page 95).•Use the MAC Filtering screen to allow or deny wireless stations based on their MAC addresses from connecting to the NBG2105 (Section 13.9 on page 97).13.1.2 What You Should KnowEvery wireless network must follow these basic guidelines.• Every wireless client in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.• If two wireless networks overlap, they should use different channels.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.• Every wireless client in the same wireless network must use security compatible with the AP.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.SSIDNormally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.AuthenticationAuthentication is the process of confirming a client’s user name and password when they connect to a network. Turning off authentication means allowing anyone to connect to the network.EncryptionWireless networks can use encryption to protect the information that is sent in the wireless network. It is the process of taking data and encoding it, usually using a secret code, so that it becomes unreadable unless decrypted with the proper code or pass phrase. If you do not know the secret code, you cannot understand the message.
Chapter 13 Wireless LANNBG2105 User’s Guide 85WEPData Encryption WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the NBG2105 and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.Authentication Type The IEEE 802.11b/g/n standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Both, Open and Shared.• Open mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.• Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer.• Both authentication mode allows the NBG2105 to switch between the open system and shared key modes automatically. Use this mode if you do not know the authentication mode of the other wireless stations.WPA-PSK and WPA2-PSK Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication.Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP)If both an AP and the wireless clients support WPA2-PSK, use WPA2-PSK for stronger data encryption. If the AP or the wireless clients do not support WPA2-PSK, just use WPA-PSK. Select WEP only when the AP and/or wireless clients do not support WPA-PSK or WPA2-PSK. WEP is less secure than WPA-PSK or WPA2-PSK.
Chapter 13 Wireless LANNBG2105 User’s Guide86MAC Address FilterEvery wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s Guide or other documentation.You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.WPSWiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices.

NBG2105 User’s Guide 99CHAPTER 14Firewall14.1 OverviewThis chapter shows you how to enable and configure the NBG2105 firewall settings.The NBG2105 firewall is a packet filtering firewall and restricts access based on the source/destination computer network address of a packet and the type of application. 14.2 What You Can Do•Use the Port Filtering screen to apply filtering based on UDP or TCP port numbers (Section 14.4 on page 100). •Use the IP Filtering screen to apply filtering based on IP addresses (Section 14.5 on page 101).•Use the MAC Filtering to apply filtering based on MAC addresses (Section 14.6 on page 101).•Use the URL Filtering to apply filtering based on URLs (Section 14.7 on page 102).14.3 What You Need To KnowThe following terms and concepts may help as you read through this chapter.What is a Firewall?A "firewall" is a system or group of systems that enforces an access-control policy between two networks. Of course, firewalls cannot solve every security problem. Guidelines For Enhancing Security1Change the default password via Web Configurator. 2Think about access control before you connect to the network in any way, including attaching a modem to the port. 3Limit who can access your router. 4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.
Chapter 14 FirewallNBG2105 User’s Guide1005For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. 6Keep the NBG2105 in a secured (locked) room. 14.4 Port Filtering ScreenClick Firewall > Port Filtering to apply filtering based on UDP or TCP port numbers.Figure 62 Firewall > Port Filtering The following table describes the labels in this screen.Table 51 Firewall > Port FilteringLABEL DESCRIPTIONEnable Port Filtering Click this to apply filtering based on UDP or TCP port numbers.Port Range Enter the port number or range of ports that define the traffic type.

Chapter 17 TroubleshootingNBG2105 User’s Guide126What factors may cause intermittent or unstabled wireless connection? How can I solve this problem?The following factors may cause interference:• Obstacles: walls, ceilings, furniture, and so on.• Building Materials: metal doors, aluminum studs.• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.To optimize the speed and quality of your wireless connection, you can:• Move your wireless device closer to the AP if the signal strength is low.• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones.• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. • Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary.• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet. • Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the antennas in different directions and check which provides the strongest signal to the wireless clients.
